How rare is a straight flush really?

Extremely — there are only 40 straight flushes in total (ten possible sequences per suit, across four suits, four of which are royal flushes) among the 2,598,960 possible five-card hands from a 52-card deck. Expect to deal about 65,000 hands, on average, before seeing one.

How this generator works

Five cards are drawn without replacement from a freshly shuffled 52-card deck using your browser's cryptographically secure random generator, then the five-card hand is classified against the standard poker ranking from high card up to a royal flush. Because there is no replacement, the same card can never appear twice in one hand, matching how a real deck behaves.

Limitations and good to know

Hands are dealt at random from a full deck, so the frequencies match real odds — a full house appears roughly once in every 700 hands, and you will wait a long time for a straight flush. Nothing here plays a game or bets; it deals and names hands, and the name appears only when exactly five cards are drawn.
Each deal is a fresh, independent shuffle of the full deck — there is no shared table, so this cannot deal remaining cards to a second player after the first hand is drawn.
